7.7 Maintaining Oxygen sensor
The oxygen measurement is based on the principle of a galvanic cell. The monitored gas diffuses
through a membrane into the electrolyte in the sensor. The electrolyte contains aworking electrode
and a reference electrode. The oxygen is reduced electrochemically and the resultant current is
proportional to the O2 partial pressure in the gas.
